Ruff the bird

he Ruff is a medium-sized wader that breeds on marshes and wet meadows across northern Eurasia. This highly gregarious sandpiper is migratory, and sometimes forms huge flocks in its winter grounds, which include southern and western Europe, Africa, southern Asia and Australia. It is usually considered to be the only member of its genus, and the Broad-billed and Sharp-tailed Sandpipers are its closest relatives. The Ruff is a long-necked, pot-bellied bird. This species shows marked sexual dimorphism; the male is much larger than the female, and has a breeding plumage that includes brightly coloured head tufts, bare orange facial skin, extensive black on the breast, and the large collar of ornamental feathers that inspired this bird's English name. The female has one brood per year and lays four eggs in a well-hidden ground nest, incubating the eggs and rearing the chicks, which are mobile soon after hatching, on her own. The Ruff forages in wet grassland and soft mud, probing or searching by sight for edible items. It primarily feeds on insects, especially in the breeding season, but it will consume plant material, including rice and maize, on migration and in winter. Classified as "least concern" on the IUCN Red List criteria, the global conservation concerns are relatively low because of the large numbers that breed in Scandinavia and the Arctic.
